Unformatted text preview: Solution: The height of the block initially is: h = 2.0 sin 25 = 0.845 m The gravitational potential energy at the top is: mgh = 149.2 J At the bottom of the ramp, all of the energy is converted to kinetic energy. However, the block loses all of its kinetic energy due to friction, eventually coming to rest after a distance d . Thus: mgh = Fd But F = N= mg Thus, mgh = mgd and solving for : = h/d= 0.28 Note that you do not need to compute the kinetic energy!...
